“…Our data (Table ) show that recruitment of wild individuals into a field from the margin is not uniform and this presumably reflects local population differences, at least in the immediate vicinity of the field edges. Because wireworm populations are strongly associated with grass (Parker & Seeney, ; Hermann et al ., ; Milosavljević et al ., ), it might be expected that grass at the field boundaries would drive these differences. This is largely borne out by reference to the descriptions in Table , although we note that the effect is more complex than the proximal presence or absence of grass, and we have also presented evidence for click beetles reaching a field via terrain other than grass, including bare soil.…”

1 Mark-release-recapture was used to investigate the dispersal of click beetles in spring wheat or fallow fields using edge or centre field releases. Three types of pitfalls were used: gutter traps near field margins, as well as conventional pitfall traps or cross-traps consisting of four gutter trap arms leading to a central pitfall. Capture of naturally occuring beetles was concurrently recorded. 2 In total, 6952 marked Agriotes obscurus (males and females) and Agriotes lineatus (males) were released and 14.74% were recaptured at some time during the present study. Recovery rates ranged from 3.54% to 28.5%. 3 Agriotes obscurus dominated wild populations, with 4011 males and 1672 females trapped compared with 17 males and three females for A. lineatus. Males dominated early in the period, although the sex ratio tended towards equality as the season progressed. 4 Generally, captures of A. obscurus males released in equal numbers at field edges followed a uniform distribution. There were differences for wild beetles caught in the same traps. 5 Spatial trapping patterns of wild and marked beetles across the fields were similar.Within 19 h of release at the field edges A. obscurus males were captured >30 m away. 6 The crop type had a significant interspecific effect on trap counts for males and an intraspecific effect on A. obscurus females, reinforcing the need for caution when using trapping systems to monitor adult stages of these pests. 7 The results of the present study demonstrate that uncropped field margins comprise sources of click beetles. We also conclude that click beetles disperse much further than reported previously.

“…However, for A. ustulatus , a negative correlation has been observed between spatial distribution of larval population and grass cover [ 104 ]. Another positive correlation is generally found with soil bulk density [ 13 , 96 , 101 , 103 ]. Correlations between soil humidity and infestation rate have also been reported [ 104 , 105 ].…”

“…Crop rotation, availability of food resources through the season, climatic-agronomic features and soil characteristics are the main known factors influencing the composition of species communities and larval population density [ 57 ]. At the local scale, site-specific variables seem to show a positive association with the level of infestation, like grass duration (or surrounding grassy margins and weedy spots) [ 2 , 13 , 96 , 101 , 102 , 103 ]. The presence of meadows and double cropping within the rotation cycles would result in a population increase of species overwintering as adults [ 57 ].…”

Wireworms (Coleoptera: Elateridae) are important soil dwelling pests worldwide causing yield losses in many crops. The progressive restrictions in the matter of efficient synthetic chemicals for health and environmental care brought out the need for alternative management techniques. This paper summarizes the main potential tools that have been studied up to now and that could be applied together in integrated pest management systems and suggests guidelines for future research.

“…A survey of A. lineatus and A. obscurus distributions over 950 ha of mixed farmland led to the conclusion that uncropped areas (field margins) were important population sources for invading nearby crops (17). This view has been reinforced in a study that related potato (S. tuberosum) damage caused by wireworms with landscape features and reported a significant correlation with grassy field margins (63).…”

Wireworms, the larvae of click beetles (Coleoptera: Elateridae), have had a centuries-long role as major soil insect pests worldwide. With insecticidal control options dwindling, research on click beetle biology and ecology is of increasing importance in the development of new control tactics. Methodological improvements have deepened our understanding of how larvae and adults spatially and temporarily utilize agricultural habitats and interact with their environment. This progress, however, rests with a few pest species, and efforts to obtain comparable knowledge on other economically important elaterids are crucial. There are still considerable gaps in our understanding of female and larval ecology; movement of elaterids within landscapes; and the impact of natural enemies, cultivation practices, and environmental change on elaterid population dynamics. This knowledge will allow generation of multifaceted control strategies, including cultural, physical, and chemical measures, tailored toward species complexes and crops across a range of appropriate spatial scales.
